What can divide equal with 7 and 9 and 3?

The number that can divide equally with 7, 9, and 3 is their least common multiple (LCM), which is the smallest multiple that all three numbers share. To find the LCM of 7, 9, and 3, you first need to find the prime factorization of each number: 7 = 7, 9 = 3 x 3, and 3 = 3. Then, you take the highest power of each prime factor that appears in any of the factorizations: 7 x 3 x 3 = 63. Therefore, 63 is the number that can divide equally with 7, 9, and 3.
